Given: Ag⁺(aq)+ E^- → Ag(s)E° = +0

Given: Ag⁺(aq) + e^- → Ag(s) E° = +0.799 V AgI(s) + e^- → Ag(s) + I^-(aq) E° = -0.152 V
Ni²⁺(aq) + 2 e^- → Ni(s) E° = -0.267 V
Which of the following reactions should be spontaneous under standard conditions?
I.2 AgI(s) + Ni(s) → 2 Ag(s) + 2 I^-(aq) + Ni²⁺(aq)
II.Ag+(aq) + I^-(aq) → AgI(s)

A) I and II are both nonspontaneous.
B) I is nonspontaneous and II is spontaneous.
C) I is spontaneous and II is nonspontaneous.
D) I and II are both spontaneous.
